Huggable Po gets all touchy-feely in "Kung Fu Panda 2," a sturdy sequel to the 2009 blockbuster. This entry aims to expand the series both in storytelling terms and visually. It introduces emotionally complex issues, and literally adds new scope via 3-D. In each case, the payoff is impressive.

The movie opens with a ravishing replica of traditional Chinese shadow puppet plays. The prologue introduces the movie's new villain, a militarist peacock named Lord Shen, who aims to conquer China by exterminating kung fu.

Po, a giant panda who transformed himself from a dumpling-shaped layabout to a mighty martial arts master, leads his Furious Five posse against Lord Shen's "unstoppable" new weapon. But pride may be his undoing unless he can find spiritual harmony as his mentor Master Shifu instructs. Haunted by memories of infancy and always a bit at odds with his fussbudget dad -- how can a goose sire a panda? -- Po lacks inner peace. He will have to subdue his own demons before he can vanquish his foe.

The vocal cast is fine, with Jack Black alternately laconic and lunatic as Po and Gary Oldman all silken menace as Lord Shen, whose claws and tail feathers double as rapiers. Angelina Jolie's strong, protective Master Tigress moves to the forefront of Po's team as Po's surrogate Tiger Mother, embodying the strict Chinese parenting that the immature hero still needs. Her colleagues Jackie Chan, Seth Rogen, David Cross and Lucy Liu get about two lines apiece. But that's fine because it gives more room to Michelle Yeoh as a soothsaying mountain goat who nervously nibbles at her clients' robes when not dispensing wisdom, and James Hong as Mr. Ping, Po's proud papa.

The film's richly textured visuals will leave you breathless. The screen is almost radioactive with beauty. The backgrounds are photorealistic landscapes of National Geographic magnificence, the interiors are fever dreams of Ming Dynasty splendor, and the character animation, with complex but extremely smooth kung fu choreography, simply flows. Fireworks are a key element of the story, and the sheer surfeit of visual delights -- more than the eye can absorb in any one moment -- mirrors the climax of a fireworks display.

There's dizzy slapstick wit to the fighting. In one scene Po and friends hide in a street-dance dragon that seemingly gobbles up Lord Shen's wolf henchmen and expels them out the other end. A climactic naval battle puts "Pirates of the Caribbean" to shame as it whittles an armada of long ships into chopsticks. Magical as the slick 3-D scenes are, the antique shadow play that opens the movie is even cooler.

Screenwriter Charlie Kaufman ("Being John Malkovich," "Adaptation") did a script polish, no doubt adding the notes of soul-searching and doubt that peck at Po. That master of fairy-tale menace, Guillermo del Toro ("Pan's Labyrinth," "Hellboy"), is credited as a creative consultant, sharpening the talons of Lord Shen, I'd wager. And the gag writers are ever-inventive: In one absurd exchange, Po, atop a towering roof, shouts a challenge to Lord Shen, who can't make out a word he's saying. There's an intimidating number of moving parts in a project such as this, and director Jennifer Yuh keeps it all running smoothly. The effort must have been considerable. The result is worth it.
